. 19 Claims. (of. 80-43) Thisinvention relates to apparatus for rod 23 which are disposed in engagement with the mills, and more especially to apparatus for conroller engaging surfaces of the arms 19. trolling and directing a rod between successive Rollers 24 also form a part of the levers 21 and reductions of a rod mill. v are di p d in e a ement with roller engaging 5 The primary object of this invention is to plates or portions indicated at 25 which are provide a simple, eflicient,'and practical apparadisposed upon the under surface of .thereceiving tus for receiving and dispensing rods in the portion 14 of the table 10. Counterweights 26 process of reduction and insures the proper, are fixed tothe shaft 11 for a purpose hereinaccurate, and positive directing of the rod. after described. 1

10 According to the objects of the invention, an Y A rigid tapered chute or guide 27, which is element is actuated by the movement of a rod rigidly mounted upon the base units 13, is, for looking a receiving table until the entire rod adaptedto receive the bars passedfrom the table is thereupon, and an auxiliary. means is pro-- and direct the bars into a rolling apparatus vided for releasing the table, whereby the table indicated as 28.

The actuating lever 29 ex- 20 lowing detailed description when considered in tends over a stationary table 31 which is in connection with the accompanying drawings, general alignment with the table 1.0 when the wherein 7 latter is in receiving position. A gear segment Fig. 1 is a fragmentary top plan view of the 32 is mounted upon the shaft 30 and arranged apparatus for receiving and dispensing rods; to be actuated by the actuation of the lever 25 Fig. 2 is an elevational view of the apparatus 29. The segment 32 is. in mesh with a. toothed shown in Fig. 1; portion 33 of an actuating cam 34, which is Fig. 3 is an enlarged top plan view of the pivotally mounted at 35, and provided with a table locking and releasing mechanism; cutaway, cam portion 36 which tapers into a Fig. 4 is a rear elevational view of the mecharetaining cam portion 37 as indicatedat 38. A nism shown in Fig. 3 and retaining latch 39 is pivotally mounted at 40 35 Fig. 5 is an enlarged end elevational view of andis provided with a roller 41 which'is held the apparatus, showing the table infull lines in in engagement with the actuating cam 34 by the receiving position and in dotted lines in the means of a tension spring 42. The latch 39 is dispensing position. provided with a jaw portion 43 which is ar- 35 Referring particularly to Figs. 1 and 2, the ranged toengage with the adjacent arm 19 at apparatus for receiving and dispensing rods con- 44 so as to hold table 10 positively in theresists of a table 10 formed of a plurality of table ceiving position. A tension spring 45 has one sections whic are Pivotally m d up n 9- end adjustably secured to the segment 32, by common s af 11. The shaft 11 is pivotally the adjustable means indicated at 46,-and the 40 supported y hearing members 12 wh a e other end secured to the adjacent base unit 13. mounted upon base units-13. The table sections A safety spring 47 s one end secured to the are provided with receiving portions 14 (Figs. segment 32 at 48 and the other end secured to 1 and 5) which are normally in a horizontal a safety lever 49, which is mounted'upon the position and stationary guide members 15' shaft 30 and whichis arranged to engage with 45 which are normally in a vertical position. A a pin 50, the latter being carried by the segmovable rod guide 16 extends above the free nt 32, A stop 51 is provided for holding the ed 17 0f the table 10 when the table segment'32 against further movement in one is in the receiving position, and is carried by dire tion, I brackets 18 wh ch are mounted 1111011 and k y From the foregoing description of the various 50 to the shaft 11. The brackets 18 are arranged parts of this apparatus, the operation thereof with integral arms 19 which have-rollerengagmay b more clearly d t d The b 1 ins r aces 20 thereupon dicated at 52, in passing from the preceding The brackets 18 are operatively associated operation, passes with suflicient'force to carry with actuating levers 21 which in turn are fixed it onto the table 10 and beyond the actuating to an auxiliary shaft-22. The levers 21 have rollers mechanism shown in Fig. 3 without additional moving force. As the bar moves across the stationary table 31 the lever 29 is actuated, due to the engagement of the bar therewith, thus actuating the segment 32 against the tension of the spring 45 and imparting a clockwise rotative movement to the actuating cam 34. This movement of the actuating cam 34, imparts an inward movement to the retaining latch 39, about its pivot 40, due to the engagement of the roller 41 with the same surface 38. The latch 39 is held in this position by the engagement of the roller 41 with the cam surface 37 during engagement of the bar with the actuating lever 29.

As soon as the bar has passed mechanism and has reached a position entirely upon the table 10, the actuating lever' 29 will be released, allowing the spring 45 to return the segment 32-to its normal position, thus rotating the actuating cam 34 in a counter-clockwise direction and allowing the latch 39 to bewithdrawn from its engagement with the arm 19 by means of the spring 42, and by means of the roller 41 engaging with the cam surfaces 38 and 36.

Immediately upon the release of the latch 39, the table 10 will be moved about the shaft 11 as a pivot due to the weight of the bar upon the table and consequently a faster movement to the movable rod guide 16 due to the engagement of thelever 21 therewith will result. It will be observed by viewing Fig. 5 that the arm of the lever 21 upon which the roller 24 is mounted, relatively short compared with the arm upon which the roller 23 is mounted. Therefore, the movement of the lever 21, due to its engagement with the table 10, will move the movable guide 16 faster than the table, thus positioning the movable guide beyond the free edge of the table when the table is in the lowennost position. When the table is in this position the bar is allowed to pass from the table upon the chute 2'7 and into the rolling apparatus 28.

After the bar has passed from the table 10, the counter-weights26 will impart a movement to the brackets 18, thus moving the guide 16 into its normal position, and at the same time moving the table 10 into its normahposition, due to the operative engagement of the lever 21 with the table. The table is now in readiness for receiving another or succeeding bar.

With this construction, it is obvious that a positive means is provided for receiving and dispensing the bars from one operation to another, and that the dispensing of the bars is accomplished by an eflicient mechanical means which is actuated by the movement and weight It will be further observed that the of the bar. device is positive in its action and serves to prevent the actuation of the table '10 until the bar has completely passed thereupon as the actuating mechanism cannot be released until the bar has passed this point and onto the table.
